Installation of an Elios (wall-mounted range) wall-mounted heat pump in Saint-Léonard

Precise comfort and discreet aesthetics in a Montreal home

In a family home in Saint-Léonard (Montreal) , our clients wanted efficient cooling in the summer and economical heating support in the fall and spring, without adding to the decor. We recommended anElios wall-mounted heat pump , known for its understated design, quiet operation , and temperature stability in the living areas. The interior head is integrated above the mirror in the entrance-living room, as close as possible to the ceiling , for uniform sweeping and optimized performance.

Project objectives and site constraints

• Improve comfort in the open area (entrance–living room–dining room), exposed to solar gain in the afternoon.

• Reduce the bill for existing electrical heaters during the off-season.

• Preserve aesthetics : no excessive projections, no visible cables , and a shutter that diffuses without creating a direct air current in the circulation area.

• Respect the clearances near the ceiling molding and wall elements (mirror, photo frames).

Expected result: a stable temperature , simplified maintenance and a sober visual rendering - three criteria on which we systematically stake our reputation.

HVAC System Design: Cleanliness of the Path and Reliability

Inner head positioning

The Elios head is centered at the top, with sufficient upper clearance for suction. This position allows:

• a cross-flow of air that sweeps across the open area without directly hitting the occupants;

• limited stratification thanks to the return of air from below and continuous recirculation;

• easy access to the hood for cleaning the filters.

Refrigeration and feeding route

• Estimated refrigeration length : ~4 to 5 m to the external condenser, on the side facade.

• Drilling : single, correct diameter, sleeved and sealed (vapor barrier + cellular foam) to prevent air and moisture infiltration.

• Chute : white in low relief, tight fittings, aligned with the moldings to remain almost invisible in the room.

• Communication and power cabling : common routing in duct, marked and accessible for service.

• Dedicated power supply ** 208/230 V** with compliant circuit breaker; panel marking for unambiguous future intervention.

Condensate management

The facade installation allowed for gravity drainage : continuous slope, non-return and discreet outlet on the outside. This solution eliminates the risk of overflow, limits noise and simplifies maintenance . When gravity is not possible, we offer a silent mini-condensate pump ; here, it remained unnecessary thanks to the choice of the wall.

AirGreen Methodology: From Copper to Comfort

1. Pre-inspection : validation of clearances, support, aesthetic constraints (mirror, frames), electrical routing.

2. Preparation of connections : large radius bends, calibrated flares and brazing under nitrogen if necessary.

3. Leak test : high pressure nitrogen immersion and drop control.

4. Vacuum draw : ≤ 500 microns , stabilization, then isolation of the pump to check the rise.

5. Commissioning : load opening, cold/hot tests , verification of blowing temperatures and intensities.

6. Fine adjustments : fan speed, orientation of the shutter to avoid direct airflow on the passage, activation of night mode .

7. Customer delivery : remote control demonstration, HVAC maintenance schedule, seasonal usage advice.

Results observed: silence, stability, sobriety

After switching on, the Elios blower quickly achieves a cool, even blow . Owners note:

• a very low noise level in the living room, ideal for TV evenings and children's naps;

• a significant reduction in heat peaks in the late afternoon;

• a clean aesthetic : the chute follows the line, and the head aligns with the high molding, without disturbing the decoration.

Essential technical details (excerpt)

• Type : Elios wall-mounted heat pump , indoor head with digital display.

• Vanes : automatic vertical sweep , directed adjustment to never blow directly on the occupants.

• Power supply : 208/230 V, dedicated circuit, 15 A or 20 A circuit breaker depending on the capacity chosen.

• Connections : insulated copper, coupler fittings tightened to the prescribed torque, butyl tape on the external terminations.

• Condenser : placed on anti-vibration pads with compliant clearances, orientation of air discharges away from nearby windows.

• Control : infrared remote control; Wi-Fi option available on request for remote management and energy optimization.

Sizing Tips for a Saint-Léonard House

• Surface area & envelope : a well-insulated open area often covers 9k to 12k BTU ; the presence of large openings, open kitchen and upper floor can justify 15k BTU .

• Orientation : western sunlight increases air conditioning needs at the end of the day; allow for margin rather than undersize.

• Acoustics : in semi-detached housing, the choice of supports and the distance between the rooms guide the placement of the condenser.

HVAC Maintenance: Maintaining Performance Over 12 Months

• Filters : rinse every 4 to 6 weeks during peak periods.

• Evaporator : annual professional cleaning (bio-cleaner, gentle brushing of the fins).

• Condenser : free clearances, rinsing of fins in spring, checking of fixings and silent blocks.

• Drain : check slope and insect trap ; purge at the start of summer.

• Electricity : Tightening inspection, circuit breaker and cable insulation testing.

What we deliberately avoided

• Multiple drillings : a single clean, sleeved hole to preserve the wall's watertightness.

• Visible cables : everything is covered in a low-projecting corner cable duct.

• Uncomfortable blowing : orientation of the shutter programmed and memorized to avoid drafts in the passage area.

• Vibrations : silent blocks and precise leveling of the condenser to protect interior peace and quiet and the neighborhood.

Grants and compliance in Quebec

High-performance wall-mounted heat pumps may be eligible for provincial incentives based on power , efficiency , and cold climate suitability. At AirGreen, we validate eligibility on a case-by-case basis, prepare the documents , and provide support until you receive the grants. Our team also certifies electrical compliance and adherence to municipal requirements .

AirGreen feedback: what makes the difference

• Design of the route before drilling: avoid tight bends and oil pockets.

• True deep vacuum : micron stability control rather than just instant reading.

• Aesthetic details : channel alignments, white screws , joint repairs; this is what customers notice on a daily basis.

• Service : We keep the installation history (lengths, test pressures, serial numbers) to simplify each maintenance .
